We created our Women's Pyre Hunting Bib with two things in mind. Number one, it's made to help you laugh at extreme cold without the bulk. The Pyre's articulated legs feature Primaloft® Silver for lightweight warmth and ease of movement. Number two, it's made for going #1. When nature calls, ladies, you don't have to remove the entire bib to do your business. As we said: designed by women, for women.
